Blood test apparatus and method of controlling the same
First Claim
1. A blood test apparatus configured for puncturing skin and measuring blood, the apparatus comprising:
- a puncturing section that punctures the skin;
a blood sensor that collects and analyzes the blood flowing out from the punctured skin;
a holder that holds the blood sensor;
a negative pressure section that supplies a negative pressure to near the blood sensor;
a negative pressure controlling section that controls the negative pressure section, wherein;
the blood sensor integrally forms a blood sensor unit with the holder;
the blood sensor unit comprises;
a chassis that has both ends open such that one end of the chassis is configured to be detachably attached to an apparatus body and the other end of the chassis is configured to contact the skin, an attaching section to which the blood sensor is attached and which is provided within the chassis, and a skin contact sensor that is provided in the blood sensor or in the attaching section, and detects contact of the skin; and
the negative pressure controlling section stops supply of the negative pressure from the negative pressure section based on a detection result in the skin contact sensor.

Abstract
A blood test apparatus having a simple constitution whereby stable measurement can be conducted by surely sampling the blood in an amount being small but sufficient for the test without placing too much burden on a patient. When a first skin contact sensor of this apparatus detects the skin, driving of a negative pressure unit is initiated. Thus, the skin rises and comes into contact with a second skin contact sensor. After piercing into the skin, the negative pressure supply is once ceased. Next, the negative pressure is applied again for a definite period of time. Thus, the opening in the skin is broadened, which facilitates the flow out of the blood.
